Understanding the Performance of Modified Asphalt
Binders in Mixtures: Evaluation of Moisture Sensitivity

Primary Topic: Materials-Concrete

Description: This report documents the effects of polymer-modified asphalt binders on moisture sensitivity. It is part of a research study titled "Understanding the Performance of Modified Asphalt Binders in Mixtures." Funding for this study is from National Cooperative Highway Research Program (NCHRP) Project 90-07. The objective of NCHRP 90-07 is to determine if asphalt binder performance is captured by the Superpave asphalt binder specification developed under the 1987 to 1993 Strategic Highway Research Program, with an emphasis on evaluating the performances of mixtures containing polymer-modified asphalt binders with identical Superpave performance grades but varied chemistries. Asphalt binder tests developed under NCHRP Project 09-10, titled "Superpave Protocols for Modified Asphalt Binders," are also being evaluated. NCHRP Project 09-10 was completed in February 2001.
